Arlington: I've been working out five-ish days a week doing cardio and weights for the last three months in preparation for my June wedding (and just to get in better shape). I've noticed a big difference already! Question: I've been increasing my weights as I get stronger, but should I keep adding or just stay where I am? I want to tone, and I'm not sure what's best. For example, I've been using 12-pound weights for shoulder exercises -- do I up that when I'm ready or just keep using the 12-pounders?

Howard: Women on the chat often worry about bulking up from lifting weights, and we remind them about the T-word, testosterone. Without it, the muscle growth won't be that profound. So if the 12-pound weights are feeling manageable, go ahead and bump it up.

But why only the shoulders? We are a nation of back-pain sufferers, and you can trace that to lack of use. . . . I know you want those shoulders looking good in the gown, but don't neglect the rest of the upper body.

Treadmill vs. Road: I had a personal trainer tell me that part of why it's easier to run on a treadmill is that the belt helps pull you along vs. you having to push your own body weight when running outside. Also, there is no cushioning on the road vs. the treadmill, so it's all in all just harder on your joints, etc.

Howard: The assist effect can be countered with incline or speed.
